Tuberculosis IRIS
Antiretroviral therapy (ART), while essential in combatting tuberculosis (TB) and HIV coinfection, is often complicated by TB-associated immune reconstitution inflammatory syndrome (TB-IRIS). Depending on the TB diagnosis and treatment status at ART initiation, this immune-mediated worsening of TB pathology can take the form of paradoxical TB-IRIS, unmasking TB-IRIS. Each form of TB-IRIS has unique implications for diagnosis and treatment. This entry is a discussion of TB-IRIS with an expanded focus on CNS TB-IRIS given its severe outcomes and anatomic and immunologic peculiarities.

Ensembl Genomes
Ensembl Genomes is a scientific project to provide genome-scale data from non-vertebrate species. The project is run by the European Bioinformatics Institute, and was launched in 2009 using the Ensembl technology. The main objective of the Ensembl Genomes database is to complement the main Ensembl database by introducing five additional web pages to include genome data for bacteria, fungi, invertebrate metazoa, plants, and protists. For each of the domains, the Ensembl tools are available for manipulation, analysis and visualization of genome data. Most Ensembl Genomes data is stored in MySQL relational databases and can be accessed by the Ensembl Perl API, virtual machines or online. Ensembl Genomes is an open project, and most of the code, tools, and data are available to the public. Ensembl and Ensembl Genomes software uses a "permissive Apache-style open-source" license, making it free for all users.

Hearing Impairment
Hearing impairment (HI), also referred to as hearing loss, is the partial or total loss of hearing. GJB2 is the most common gene associated with HI and it belongs to a family of genes that encodes connexin proteins. Over seven connexins (GJB3, GJB4, GJC3, GJC1, GJB2, GJB6, and GJA1) have been globally studied for their association with HI, however, the majority did not have a clearly established association with the condition. Although there were studies that reported variants in  GJB3, GJB4, GJC3, and GJC1 in hearing-impaired patients, there is a need for more studies to clearly describe their role in the development of HI. GJB2, GJB6, and GJA1 on the other hand have been identified as HI genes that should be considered in routine clinical investigations. Recent data has shown that the coding region variants of GJB6 (except the large genomic deletions) do not contribute to the development of HI.

Social Image of Nursing
Nursing is a discipline on which stereotypes have persisted throughout its history, considering itself a feminine profession and subordinated to the medical figure, without its own field of competence. All this leads to an image of the Nursing Profession that moves away from reality, constituting a real, relevant and high-impact problem that prevents professional expansion, and that has a direct impact on social trust, the allocation of resources and quality of care, as well as wages and professional satisfaction.

Stingless Bee Honey as Antidepressant
Depression is a debilitating psychiatric disorder impacting an individual’s quality of life. Conventional treatments include tricyclic antidepressants (TCAs), norepinephrine–dopamine reuptake inhibitors (NDRIs), monoamine oxidase inhibitors (MAOIs), and serotonin reuptake inhibitors (SSRIs). Despite numerous pharmacological strategies utilising conventional drugs, the discovery of alternative medicines from natural products is a must for safer and beneficial brain supplement. Stingless bee honey (SBH) has been proven to contain a high level of antioxidants compared to other types of honey.

Obesity Pathogenesis: Role of CNS
Obesity is a serious health problem because it is rapidly expanding and at the origin of intense morbidity and mortality, especially due to the diabetes that accompanies it.It is not possible to cure it effectively, except with bariatric surgery, which is highly invasive and with many limitations. Trying to understand the mechanism of this efficacy, the studies point towards the correction of the altered control by the CNS of food intake and energy homeostasis. At the biomolecular level, the possibility of a pharmacological therapy based on the modulation of the post-synaptic receptors of glutamate, in particular of the NMDA GluN2A and GluN2B subunits, is foreseen.

Therapeutic Approaches Utilizing Macrophage-Derived iNOS/NO in Cancer
Nitric oxide and its production by iNOS is an established mechanism critical to tumor promotion or suppression. Macrophages have important roles in immunity, development, and progression of cancer and have a controversial role in pro-and anti-tumoral effects. The tumor microenvironment consists of tumor-associated macrophages (TAM), among other cell types that influence the fate of the growing tumor. Depending on the microenvironment and various cues, macrophages polarize into a continuum represented by the M1-like pro-inflammatory phenotype or the anti-inflammatory M2-like phenotype; these two are predominant, while there are subsets and intermediates. Manipulating their plasticity through programming or reprogramming of M2-like to M1-like phenotypes presents the opportunity to maximize tumoricidal defenses. The dual role of iNOS derived NO also influences TAM activity by repolarization to tumoricidal M1-type phenotype. Regulatory pathways and immunomodulation achieve this through miRNA that may inhibit the immunosuppressive tumor microenvironment.

Infection Control
Infection control is the discipline concerned with preventing nosocomial or healthcare-associated infection, a practical (rather than academic) sub-discipline of epidemiology. It is an essential, though often underrecognized and undersupported, part of the infrastructure of health care. Infection control and hospital epidemiology are akin to public health practice, practiced within the confines of a particular health-care delivery system rather than directed at society as a whole. Anti-infective agents include antibiotics, antibacterials, antifungals, antivirals and antiprotozoals. Infection control addresses factors related to the spread of infections within the healthcare setting (whether patient-to-patient, from patients to staff and from staff to patients, or among-staff), including prevention (via hand hygiene/hand washing, cleaning/disinfection/sterilization, vaccination, surveillance), monitoring/investigation of demonstrated or suspected spread of infection within a particular health-care setting (surveillance and outbreak investigation), and management (interruption of outbreaks). It is on this basis that the common title being adopted within health care is "infection prevention and control."

An Instrument for Occupation-Based Research
Occupational therapy practice is based on the fundamental assumption that meaningful occupations play a key role in achieving and maintaining health and wellbeing by facilitating personal engagement and accomplishment [1]. This practice framework rests largely on the fact that occupational performance should involve an occupational balance (OB), i.e., a sense of harmony between occupations, becoming a necessary condition to ensure that occupations properly perform a process for obtaining health and wellness. From an occupational perspective of health, it should be noted that there is a variety of risk factors that can affect the right use, choice, opportunity, or balance in an occupation, thereby resulting in occupational dysfunction, which may also involve other negative consequences such as occupational deprivation, occupational alienation, or occupational imbalance.

MRCPsych
MRCPsych (Member of the Royal College of Psychiatrists) is a postnominal qualification awarded to physicians who have completed the prescribed training requirements and membership examinations mandated by the Royal College of Psychiatrists. Candidates must be registered with the GMC or a recognized medical board in their own country and should have undergone three years of training. Although initially a two-part exam, the examination has undergone a radical change in the past few years, notably in terms of focus and structure. Although originally a two-part exam, the current examination is 3 parts, consisting of 2 written papers (Paper A and Paper B) and a clinical exam (CASC). Paper A focuses on Neuroscience, Pharmacology, Psychology and theory, while Paper B focuses on Current Clinical Practice & Evidence within General Adult and the various subspecialties of Psychiatry, Epidemiology, Statistics, Critical Appraisal and Psychotherapy The Royal college of psychiatrists has announced the change of format of the CASC exam changes for the exam in January 2018. The 4 linked stations in the morning session will now become 8 single stations with 4 minute to read and 7 minutes to complete the task. 6 of these will be patient management focus and the other 2 history taking. The other 8 single stations remain the same format 90 s to read and 7 minutes for the exam.

Range Anxiety
Range anxiety is the fear that a vehicle has insufficient range to reach its destination and would thus strand the vehicle's occupants. The term, which is primarily used in reference to battery electric vehicles (BEVs), is considered to be one of the major barriers to large-scale adoption of all-electric cars. The term range anxiety was first reported in the press on September 1, 1997, in the San Diego Business Journal by Richard Acello referring to worries of GM EV1 electric car drivers. On July 6, 2010, General Motors filed to trademark the term, stating it was for the purpose of "promoting public awareness of electric vehicle capabilities". The Norwegian equivalent rekkeviddeangst was assigned second place in a list of Norwegian "words of the year" for 2013 by the Norwegian Language Council. The main strategies to alleviate range anxiety among electric car drivers are the deployment of extensive charging infrastructure, the development of higher battery capacity at a cost-effective price, battery swapping technology, use of range extenders, accurate navigation and range prediction and availability of free loan vehicles for long trips. According to a study by the American Automobile Association, the cure to range anxiety is owning an electric vehicle.
